No. 6 Arizona 74, USC 50

Nick Johnson scored 14 points and Arizona used a stifling defense to bounce back from a home loss and rout Southern California.

No. 9 Butler 83, Temple 71

Rotnei Clarke scored 24 points in his return from a severely sprained neck and Khyle Marshall added 19 points, leading Butler to a victory over Temple.

It was Clarke's first game in two weeks and he looked as good as ever. The senior knocked down three 3-pointers and 13 of 14 free throws, also opening things up for teammates such as Marshall. The Bulldogs (17-3, 4-1 Atlantic 10) have won 14 of their last 15 with the only blemish since Nov. 21 coming Wednesday at La Salle.

Temple (13-6, 2-3) was led by Khalif Wyatt, who scored 16 of his 22 points in the first half. Scootie Randall had 13.

Butler used a 12-0 first-half run to take control, opened the second half on a 7-0 run to make it 44-34 and finally pulled away with a late 8-0 spurt.

Iowa State 73, No. 11 Kansas State 67

Will Clyburn had 24 points and 10 rebounds and Iowa State handed Kansas State its second straight loss.

Freshman Georges Niang added 15 points for the Cyclones (14-5, 4-2 Big 12), who beat a ranked opponent for the first time this season.

Will Spradlin had 15 points and Rodney McGruder scored 13 to lead the Wildcats (15-4, 4-2), who lost on the road for the first time in four tries.

Traevon Jackson just beat the shot clock and hit a 15-foot jumper from the right side with 4 seconds left as Wisconsin handed Minnesota its fourth straight loss.

After Jackson's shot gave the Badgers a 45-43 lead, the Golden Gophers (15-5, 3-4 Big Ten) called a timeout with 1.8 seconds remaining and inbounded from halfcourt. The Badgers' Mike Bruesewitz fouled Trevor Mbakwe on the play, but the big man was unable to shoot the ensuing free throws because of an apparent right hand or wrist injury.

Rodney Williams stepped to the line and made the first free throw, but missed the second and Sam Dekker grabbed the rebound to seal the win for Wisconsin (14-6, 5-2), which ended a two-game slide.

Andre Hollins had 20 points for Minnesota.

No. 14 Ohio State 65, Penn State 51

Sam Thompson scored 16 points on 6-of-7 shooting for Ohio State.

DeShaun Thomas added 11 points, well below his Big Ten-leading average of 20.5. Thompson picked up the slack against the Nittany Lions, who went 11-plus minutes of the first half without a field goal.

Ohio State (15-4, 5-2 Big Ten) gradually asserted control in the second half, though scrappy Penn State (8-12, 0-8) tried to hang around with defense and got within 10 points with 2:41 remaining.

Freshman T.J. Warren added 19 points for the Wolfpack (16-4, 5-2 Atlantic Coast Conference), who beat the Tar Heels for the first time in nearly six years. N.C. State dominated much of the night, leading by 23 points before the break and 28 after halftime before the Tar Heels put together a second-half push that made things interesting the final minutes.

P.J. Hairston scored 19 points to lead the Tar Heels (13-6, 3-3), including four second-half 3-pointers that helped UNC slowly climb back into the game.

No. 22 Missouri 81, Vanderbilt 59

Jabari Brown scored 21 points, Alex Oriakhi tied a career high with 18 and N Missouri cruised to a victory over Vanderbilt.

Missouri (15-4, 4-2 Southeastern Conference) led 49-20 at halftime thanks to an early 32-2 run spanning 11:47.
